Fig. 16 is an enlarged fragmentary detail of the mech-4 anism for forming the hooks on the ends of. the bail. Fig. 17 is an enlarged section Fig. 18 is a ating the machanism shown `in Fig. 18.

As shown in the drawings: A frame is provided constructed of side members 1 and a top member or table 2. Said table is provided with a central opening, as shown clearly in Fig. 6, and secured to the Atable on each side of said opening are uprights `or posts 3, connected at their upper ends by means of a plate or support 4.V A semicylindric or 'suitably shaped die member or form 5 is rigidly secured to the support 4,

and depends therefrom and extends at its lower end into the opening in thetahle 2.'

Means arev provided for feeding the wire forwardly and curving the same to pass around the die member. For this purpose a plurality of parallel shafts 6-7 are journaled in suitable bearing blocks 8 9, rigidly secured to the table 2 opposite the fiat face of the die member, and secured on the inner ends thereof are coacting grooved feeding rollers 10-11, which intermittently advance the wire strand.

For thepurpose of intermittently rotating the feeding rollers, intermeshing gears 12-13 are secured on the outer ends of the shafts 6 7, and on the shaft 7 outside the gear 13, a ratchet wheel 14 is keyed, which is inclosed by a casing 15 having pawls 16 pivoted thereto, as shown in Fig. 17, which engage the teeth of the ratchet wheel. .when rotated in one direction toactuate the feed rollers and which slide over the teethof the ratchet wheel when rotated reversely. Keyed on the hub 17 of said casing 15 is a gear 18, which meshes with a segmentI 19, pivoted to a depending bracket 20 secured to the frame, and pivotally connected at one end to said segment is a connecting rod 21, which is adjustably and eccentrically pivoted at its opposite end to a gear 22, secured on a shaft 23, journaled at one end of the frame, and said gear 22 meshes with a. pinion 24, on a drive shaft 25.

For the purpose of guiding the strand of wire to the feeding rollers and straightening the wire, a frame 26 is rigidly bolted to the frame on which are two sets of rollers 27-28, one set vertically arranged and the other set horizontally arranged. The rollers in each set are grooved and arranged staggering, and rigidly secured to the outer end of ythe frame is a guide plate 29, provided with an aperture therein through which the wire is passed to the rollers. A guideway 30 is secured to the bearing block 9, and secured therein by means of a set-screw 31 is a slide 32, on the end of which is secured a grooved bending roller 33, horizontally disposed with the grooves in position to receive the wire from between the feeding rollers 10-11, and which bends the wire on a radius slightly less than the radius of the die member to adapt the curved wire to tightly it the die member. A guide plate 34 is rigidly secured to the die member 5 at one corner thereof and is provided with an aperture 35 therein through which the wire is passed and which directs the curved wire around the die member. Pivoted between said guide plate 34 and die member 5, is a. cutter 36, which severs the strand after the length suit-able for a bail has passed. The end of said cutter 3G is provided with a head to engage in a suit-able notch in a plunger 37, which reciprocates in a` suitable sleeve 38, secured toA a bracket 39, secured to the table 2. An aperture is provided in one side of the guide cylinder 38, through which the end of an oscillating lever 40 extends which is provided on its inner end with a head to engage in a notch in the plunger 37. Said lever 40 is pivoted to a. shaft 41, supported on" the bracket 39, and the outer end thereof is provided with an anti-friction roller 42, which is operated by a cam 43, securedy on a shaft 44 journaled at the end of t-he frame opposite from the shaft 23, and said cam is timed to operate the cutter at the instant the desired length of wire has been fed past the knife. The Wire bail is now bent around the upper end of the die member 5, with the ends projecting from each corner of the die member a sutiicient distance for the forming of the hooks on the ends of the bail.

For the purpose of forcing the bails downwardly into position for forming the hooks and thence to discharge the completed bails,

a plurality of reciprocating bars 45 (as shown three in number, arranged one adjacent each corner and one intermediate the same) are provided, which slide in longitudinal dovetailed grooves in the cylindrical face of the die member and are each provided vvith three spring-pressed pawls 46, adapted to be depressed in recesses 47 in the bars by the hails when the bars are reciprocated upwardly but which engage the ba-ils on the downward reciprocation to force the same toward the lower' end of the die member 5. For the purpose of simultaneously and equally reciprocating said bars a plate 48 is secured to the upper ends thereof, said ends being reduced in diameter as shown in Fig. 12, and rigidly bolted to said plate is an arm 49, on each end of which is secured: a sleeve 50, each of which engages a guide stem 5.1 secured to the support 4. An outwardly directed bracket 52 is rigidly secured on the support 4, on which is pivoted an oscillating lever 53, the inner end of which is pivotally connected to the arm 49 by means of a link 54, and the outer end of said lever is pivoted to a connecting rod on the end of which is secured an eccentric strap 56, which engages around the eccentric 57, secured on the shaft 58, journaled at the side of the frame opposite the fceding mechanism and which is provided with bevel gears 59-60 at the ends thereof which mesh with bevel gears 61h62 on the shafts 23 and 44, and whereby all the shaftsV operate together.

For the purpose of forming the hooks on the ends ofthe bail a die 63 is set in the flat face of the die member 5 at the lower end thereof and at each corner is provided with a recess 64, Shown in Figs. 4, 6 and 1G, suitable to receive the end of the wire therein. Suitable guides G5-66 are secured to tbe table 2 on opposite sides of the opening therein and slidable therein are carriages 67-68, to each of which an adjustable connecting rod 69 is pivotally connected at one end and on the outer end of each rod is an eccentric strap 70, which engages around an eccentric 71, secured to the respective shafts 23 and 44. Transversely slidable plates 72 are secured to each carriage by means of a set-screw 73, which passes through a slot 74 in the plate and each plate is provided with an angularl-y inclined sharp edged bending linger 75, adapted to engage the end of the wire and bend the same into the recesses in the die block 63, and a pulling spring 7G secured at one end to the plate and at its opposite end to the carriage acts to shift the bending fingers out of engagement with the hooked ends of the wire to permit free retraction thereof.

For the purpose of forcing the bending fingers 75 to form the hooks at the ends of the bail and also to provide a barb in the hooked ends of the bail, ways 7 6 are secured to the under side of the table in which a carriage 77 slides, on the inner end of which are adjustably but rigidly secured cam plates 78, against which the inclined fingers 7 5 engage as the carriages 67-68 move inwardly causing the fingers to move inwardly to bend the ends of the bail to form hooks and the fingers bite into the hooks to form a barb 7 9, as shown clearly in Fig. 16. Said cams 78 are in effect stationary being shifted outwardly once during each operation just prior to the retraction of the carriages 67-68, to permit the springs 75 to throw the forming fingers outwardly from the die, but at all other times said cams are rigidly held at their inner limit of movement, as shown in Fig. 5. For this purpose a stud shaft 80 is secured to the table on which is pivoted a horizontally oscillating lever, one end 81 of which is provided with a rounded head 82, and is secured in a notch in the carriage 77 by means of a plate 83, and the opposite end 84 is provided with an anti-friction roller 85, which engages in a groove in the cam 86, secured on the shaft 23, and which is pro.- vided with a throw 87, shown in Fig. 19, which actuates the lever once during each rotation of the shaft to shift the cam plate 78 slightly outwardly suiiicient for the purpose specified.

Means are provided for preventing the` bail springing or beingforced from the die block when the hooks are being formed. For` this purpose ways 89 are secured to the table on the opposite side ofthe opening from the cam plates'7 8, and slidably secured therein is a carriage 90, on the inner end of which is secured a clamp or plate 91, concave on its inner end complementally with the curvature of the die member 5. "The-car-V riage at its outer end is reduced in thickness and provided with a cam face 92 and a pin 93, between which is slidably secured a cam bar 94, shaped on one side complementally` with the cam 92, and provided with an inclined face on its opposite side against which the pin 93 bears. A plate 95, shown in Fig. 3, is secured to the ways 89, to prevent displacement of any of the parts. l A link 96 is pivoted at one end to the cam bar 94 and at the oppositev end to a lever 97 pivoted to the table. Said lever is provided with an anti-friction roller on its outer end which engages the face of a cam 99, the throw of which is suliicient to force the plate 91 to firmly engage the bail to thedie mem ber at the proper time, j

For the purpose of retracting the car` riage 90 and plate 91, a spring 100 is secured on the reduced end of the cam bar and bears at its outer end against a lug 101 on the table, and a nut 102 is threaded on the outer end of the cam bar to limit the return ofthe cam bar to normal.` y l The operation is as follows: The end of the strand of wire is inserted through the guide aperture in the plate 29, thence led through the sets of guiding and straightening rollers 28 and 27, between the feeding rollers 10-11, around the bending roller 33, and inserted through the aperture 35 in the plate 34. The machine is now ready for operation, and power is applied. The feed rollers are rotated a distance to feed through the aperture 35 a suflicient length of wire to form the bail and the hooks, and the bending roller curves the wire to pass around the die member 5. At the moment the intermittent feed of the rollers 10-11 ceases the cam 43 on the shaft 44 actuates the lever 40, which reciprocates the plunger 37, to operate the knife to sever the-wire. After the wire is severed the eccentric 57, on the shaft 58, oscillates the lever 53, which elevates the reciprocating4 bars 45, for the pawls to engage above the bail and then depresses the bars forcing the bail downwardly on the die member without loosening the grip of the bail thereon. This is possible owing to the fact that the pawls yield inwardly on the upward stroke permitting the same to pass beneath the 'bail without jarring the same loose and when above the bail the springs force the pawls outwardly to engage the bail on the downward stroke. When the bailshave been adjusted downwardly into position for the hooks to be formed the clamp or plate 91 is operated to bear against the bail and hold the same tightly against the die member, after which the eccentrics on the shafts 23y and 44 operatethe carriages 6.7468 simultaneously inwardly carrying the bending or hook-forming fingers or members therewith, which vengage `the pro-` jecting ends of the bail and bend the same into the recesses in the die 63'. The hookformingmembers engage on the cam faces of thecams 78, and are gradually forced inwardly with great power biting into the ends'of the `bail to form a barb or catch, as shown. At the, end of the inward movement of the hook-forming members and prior to their retraction the throw87, in the cam 86, actuates: the carriage 77, to slightly retract the cam members 78, and simultaneously the springs 76 draw the hook-forming members fromjthe die'after which the carriages retract saidhook-forming members.` The leccentric 57, onthe shaft 58, has by this timeV againreciprccated the bars 45 upwardly and now reciprocates the same downwardly and one vset of pawls forces a bail into position to have the' hooks 'formed while the lowerv set of pawlsengages the bail on which the hooks have `been formed and forces the same from the die member into the guide 104, which 4conveys the bails from the machine. u It will be noted that after the knife has severed a strip of the Wire, the end of the Wire remains in the guide hole 35, in position to pass around the die member When the` feed rollers again operate.V The radius of the bail being slightly less than the radius of the die member the bail clings to the die member and cannot be jarred loose transversely of the die member. It will further be seen that the construction is such that the cam members 78 form a stationary device thereby adapting great pressure to bev eX- erted by the hook-forming members, and also that by the slight retraction thereof that said members may be Withdrawn Without friction and danger of breakage. The feed is intermittent and can be adjusted by means of the connections for the rod 21 and gear 22, to feed various lengths of strips to form bails of different length and the curvature o-f the bail may be changed by adjustment of the bending roller 33, thereby adapt-ing the machine for making various sizes of bails by replacing the die member 5 with suitable die members.

Many changes in the construction may be made Wit-hout departing from the principles of this invention, and I therefore do not desire to limit this application for patent otherwise than necessitated by the prior art.
